Note: Attaining the proper setting for the
advancement guide is a matter of patience
and trial-and-error. This setting is critical to
properly sharpen the cutters, so take the time
to find the correct setting.
The goal is to position the cutter in relation to
the grinding wheel so that all three angles—
the top plate angle, the top plate cutting
angle, and the gullet angle—will be correctly
sharpened.
14. With the machine still disconnected from
power, lower the grinding wheel into the gul-
let.
— if the wheel matches the gullet profile and is
against the top and side plates when com-
pletely lowered, the advancement guide is
properly set for now. tighten the knob lock
nut on the adjustment controls behind the
guide to secure the setting.
— if the wheel hits the top plate or depth
gauge and does not completely lower into
the gullet, or it is not against the top and
side plates, adjust the advancement guide
until it successfully stops the chain in the
proper position. Be sure to secure the set-
ting by tightening the knob lock nut.
13. position the edge of the advancement guide
behind the cutter to be sharpened, then pull
the chain to the left until the guide catches
and stops the chain (see figure 32).
11. use the clamp lever (see figure 31) to set
the gap between the clamp plates to match
the chain gauge, which will allow the chain
to easily move along the top of the clamping
bars in the same manner it moves along the
chain saw bar.
12. locate the cutter link with the shortest top
plate length and position the chain so that this
link is under the grinding wheel. this will be
the first link sharpened.
use chalk or a marker to note the first link to
be sharpened so that you will know when you
are finished with that side of cutters.
Note: If all of the top plates are approximately
the same length, then start with any cutter.
The concern is that all top plates are the
same length when the sharpening operation
is complete to ensure they cut away the same
amount during operation.
If the grinding wheel should break apart
during operation, the only thing between
you and the flying debris of the wheel are
the wheel and arbor safety gu ards. ALWAyS
make sure the wheel and arbor safety guards
are properly secured in place before con-
necting the machine to power!
